Hi all,
Holden's Recommended fuel: ULP or PULP for slightly higher performance (E10 compatible)
Just to quote an article on what fuel to use in your car from Car Advice:
“Here’s the thing: you can put a higher octane fuel in a car than the manufacturer’s requirement. No problem with putting 95 or even 98 in a car designed for 91 – except generally you will be wasting money. Higher octane fuels don’t contain more energy. Octane rating is basically resistance to burning under pressure, allowing higher compression ratios to be used (cylinder pressures, actually).
A modern engine designed for 91 will even deliver a very small amount of additional power if fed 95 or 98 because it will advance the timing a little more than with 91. The improvement will be very minor. So minor you probably won’t notice it.
Most engine design experts I’ve ever spoken to regard running higher octane fuel in an engine designed for a lower octane fuel as basically a waste of money.
However, it’s an unmitigated disaster to put a lower-octane fuel in an engine than the one recommended by the manufacturer. This can lead to severe engine damage.”

Like the Figures on your consumption, it'll be interesting to see how we all average out compared to the factory stated fuel ecenomy: see below.
Factory stated Fuel economy: (L/100km) 12.6L/100km Fuel economy based on ADR 81/02 testing for combined urban/extra urban driving. These figures are provided to assist you in comparing the fuel consumption of this vehicle with other vehicles.
"Fuel consumption depends on factors such as traffic conditions, vehicle condition, vehicle load and your driving style."
I likke this above clause because you can't hold it against their claim; their Loophole
